1. Cholinesterases Inhibition by Novel cis- and trans-3-Arylaminocyclohexyl N,N-Dimethylcarbamates: Biological Evaluation and Molecular Modeling
The present study describes the synthesis, assessment of the anticholinesterase activity and the inhibition type of novel cis- and trans-3-arylaminocyclohexyl N,N-dimethylcarbamates. In vitro inhibition assay by Ellman's method with human blood samples showed that carbamates were selective for butyrylcholinesterase (BuChE) with compound concentration that in

2. Tumor growth reduction is regulated at the gene level in Walker 256 tumor-bearing rats supplemented with fish oil rich in EPA and DHA
We investigated the effect of fish oil (FO) supplementation on tumor growth, cyclooxygenase 2 (COX-2), peroxisome proliferator-activated receptor gamma (PPARγ), and RelA gene and protein expression in Walker 256 tumor-bearing rats. Male Wistar rats (70 days old) were fed with regular chow (group W) or chow supplemented with 1 g/kg body weight FO daily (grou

3. Chlorophenols in tap water from wells and surface sources in Rio de Janeiro, Brazil: method validation and analysis
Two analytical methods were validated for determination of trichlorophenols, tetrachlorophenols and pentachlorophenol in drinking water. Limits of quantification were at least ten times lower than maximum permissible levels set by the Brazilian legislation, which are 200 ng mL-1 for 2,4,6-trichlorophenol and 9 ng mL-1 for pentachlorophenol. Chlorophenol leve

4. Construção do Conceito de Gene por meio de jogos pedagógicos
Esta pesquisa objetivou verificar o potencial de jogos pedagógicos como auxiliadores no processo de construção do conceito de gene, entre alunos de Ensino Médio. Os jogos pedagógicos, criados especificamente para este trabalho, foram testados com alunos de terceiros anos do Ensino Médio da Escola Estadual Presidente Vargas, da cidade de Dourados, Mato

5. Comparison of common carotid artery intima-media thickness between Brazilian Euro-descendants and Afro-descendants with atherosclerosis risk factors
OBJECTIVE: To compare common carotid intima-media thickness (IMT) between the two major Brazilian ethnic groups (those of African descent and those of European descent) among individuals with one or more risk factors for atherosclerotic disease. METHOD: Two hundred and six patients with one or more risk factors for atherosclerotic disease were evaluated in a

6. A practical protocol to measure common carotid artery intima-media thickness
OBJECTIVE: To describe and test a practical protocol to measure common carotid intima-media thickness that uses the combined values of two longitudinal examination angles to increase sensitivity. METHOD: Between February and September 2005, 206 patients underwent duplex scan examination of carotid vessels, and the intima-media thickness of 407 common carotid

7. Optimization methods for the definition of MLP neural network architectures and weights / Optimization methods for the definition of MLP neural network architectures and weights / MÃtodos de otimizaÃÃo para definiÃÃo de arquiteturas e pesos de redes neurais MLP / MÃtodos de otimizaÃÃo para definiÃÃo de arquiteturas e pesos de redes neurais MLP
This dissertation proposes modifications in the Yamazaki method for the simultaneous optimization of Multilayer Perceptron (MLP) network weights and architectures. The main objective is to propose a set of modifications with respective validations aimed at creating a more efficient optimization process. The optimization hybrid algorithm is based on the simul

8. Production of Ochratoxin A by Aspergillus ochraceus Isolated in Japan from Moldy Rice
A simple thin-layer chromatography-fluorodensitometric method for quantitative analysis of ochratoxin A was developed. This method proved to be of use in investigating the production of the toxin and the nutritional factors affecting the toxin production by two strains of Aspergillus ochraceus isolated from moldy rice in Japan. These fungi produced large amo

9. Genetic Analysis of Natural Populations of DROSOPHILA MELANOGASTER in Japan. II. the Measurement of Fitness and Fitness Components in Homozygous Lines
Fifty lethal-free, sterility-free isogenic lines of Drosophila melanogaster that were randomly sampled from a natural population were tested for net fitness and other components of fitness by competition with D. hydei. Larval viability and developmental time were also measured using the balanced marker method. Distribution patterns of these fitness componen

10. The Effects of Overdominance on Linkage in a Multilocus System
Computer simulations were performed with overdominant multiple alleles among tightly linked multiple loci under a multiplicative fitness model. The quantity X2/N(n — 1) was introduced as a new measure of linkage disequilibrium which, unlike previously available measures, can be applied to multiple allele models, where N is the sample size, and n is the num

11. Comparison of flow velocity of ophthalmic artery between primary open angle glaucoma and normal tension glaucoma.
AIMS--This study describes an investigation of the relation between the change of intraocular circulatory dynamics and visual field defect between primary open angle glaucoma (POAG) and normal tension glaucoma (NTG). METHODS--The method was to determine the blood flow velocity of the ophthalmic artery using colour Doppler imaging and quantitative peak systol

12. Expression of urinary H-2 odortypes by infant mice.
The extended H-2 complex of genes in the mouse includes at least three loci that independently specify distinctive body odors, "odortypes," whose differential recognition influences mating choice and affects the maintenance of early pregnancy. A prime experimental method of identifying H-2 odortypes is the specially designed Y-maze in which mice are trained,
